This is bothering me. If I leave it in drive and stomp on it, it up shifts at about 4000 to 4200 RPM. If I stick it in first, it still up shifts at around 4000 to 4200 RPM. Any idea whats going on here?

 

Pursue the easy stuff first. Adjust the tv cable per the factory specs. Check it for smoothness. If that is not it, remove the governor and inspect it. Look closely at the gear and be sure the valve moves freely when the weights are depresses in and out.

 

if u leave it in first it should stay there intill u put it in second unless u have a electronically controlled transmission but no thirdgen 700r4s came with that unless im mistaken.

least thats how mine was i wound it out to 6 grand once or twice by mistake

 

Come to think of it. This shifting thing started when I put the JET chip in.

 

putting in a jet chip shouldnt change the shift points on a mechanically controlled transmission.

 

Are you 100% sure theres no ECM functions at all? I was under the impression that there was do to the fact that you can screw around with the Tourque converter by jumpering points at the ALDL connector. I'm not doubting you, I'm just looking for correction if I've been mistaken.

 

doubt me its ok, ill be the first to say i dont know everything.

from what ive learned doing something with your computer shouldnt change your shift points for a mechanically controlled trans. like in my cars case if i have it in 3,2,1 it wont shift above watever gear its in intill i shift it. idk why yours shifts to 2 if u have it in 1. maybe your shift kit changed something, u might want to talk to people who have the same kit.

 

It's possible the Shift kit is part of the problem From what I gather theres not to many B&M fans in here. But the shifting problem definitely started with the JET chip.

 

try taking it out and see what happens.

 

This is not right. I removed the chip, My ecm was easy to access, its kind of hanging there while I troubleshoot this. Anyway with the ECM stock, the car winds out over 5000 RPM. Im confused

 

that makes two of us.


does it go to 5k+ when you have it in 1? or when in Drive?

 

In drive, depending how I feather the pedal, it will shift up at around 5000. Sometimes it will upshift way earlier depending on how I am with the pedal. If its in first, it will do pretty much the same, but it will kick itself out of gear over 5000 RPM, but then violently re-engage when the RPM comes down. With the chip, if in 1st, it will upshift to second.

 

weird my car would never shift itself out of first. but i know what you mean by violent downshift, kinda feels like u stepped on a the brakes somewhat. its fun to leave it in first and make the car jump lol.

whats the normal shift point for a tpi?

is your idle the same with the chip and without it?

 

Idle is normal and so is everything else, but the Tranny. And by violent, I mean I almost go through the window, and the rear tires chirp like Tweety pissed at sylvester.

 

the chip will only affect the lockup function of the torque convertor. follow Floor Guys suggestions and check the govenor. the only other thought might be that the chip is allowing the convertor to lock up regardless of gear selection and thereby changing fluid pressure. when your tranny drops out of gear with the factory chip, it is trying to shift but not being allowed to because of gear selection at the shifter.


by the way, got any pics of your air induction. it sounds interesting.

 

My air induction is here: https://www.thirdgen.org/forums/show...9&postcount=22

How do I go about checking the Governor?

 

remove the govenor cover to gain access to it. pull it out. inspect the gear for wear and broken teeth. then hold it by the gear with the gear up and push the the weights in and out to ensure the valve in the center of the govenor moves freely. wear on the gear or a sticking valve can make tranny's do some weird stuff when it comes to shifting.

 

Most 700R4's will come out of 1st gear at some rpm, even though the lever is still in 1st gear. Trans-Go's Performance Shift kit solves this, you can hold any gear to any rpm. (overcoming the WOT governor shift point).

 

Thanks for the info. What is the kit number and can I do this even though I have the B&M kit in it now?

 

The downside of the B&M kit is that feed holes are drilled out too large. In order to correct this a new separator plate is best. And even better news is that they are cheap. Should be around $10-$15 to replace it.

I can't help with the kit number, several years ago I used the TransGo ReProgramming kit. There may have been a name change, but it too allowed 1st to be held to any speed.

Go to http://www.700r4l60e.com/store/custo...&cat=28&page=1 This will give you all you need for performance & durability.

 

Awesome. Thanks for the help. This kit is with the vette servo I see. Now theres one other part that I need that will solve the 1/2 throttle downshift correct?

 

That kit seems to be what I'm after. My only question is will I be able to install in a Trans that has the B&M kit? Can I un-install the B&M so to speak?

 

If someone can confirm this.....I think the part # I'm after is a
Transgo 700-2-3. I' was told this is what is in the police package and other HP applications.
